Where do you create your puzzles?

As with most setters, I imagine, ideas for clues come at any time, anywhere. But for working them out I need somewhere quiet. Even background music, however gentle, is a distraction. I love silence.

And what are the tools of your trade?

I'm aware that there is a vast amount of information available at the click of a button but if I want to check something or find something out I prefer a book. So: Chambers, Roget's, Longmans, Pears – time-consuming and old-fashioned, but so am I. And a pen always within reach in case inspiration strikes.

What do you do for a living besides writing crosswords?

I enjoy a life of leisure. I'm retired.

How did you choose your pseudonym?

I've always felt vaguely guilty about not liking the name my parents chose for me. With US substituted for Y it looks and sounds a lot better, I think.
